General Description

The Am79C90 CMOS Local Area Network Controller for Ethernet (C-LANCE) is a 48-pin VLSI device designed to greatly simplify interfacing a microputer or miniputer to an IEEE 802.3/Ethernet Local Area Network.

The C-LANCE, in conjunction with the Am7992B Serial Interface Adapter (SIA), Am7996 or Am79C98 and Am79C100 Transceiver, and closely coupled local memory and microprocessor, is intended to provide the user with a plete interface module for an Ethernet network.

The Am79C90 is designed using a scalable CMOS technology and is patible with a variety of microprocessors.
